Embodiment 1

[0044] Embodiment 1, the synthesis of SOF-AP5-MJP5

[0045] (1) Synthesis of NA: 1,8-naphthalene dicarboxylic anhydride (1.98 g, 10 mmol), glycine (1.13 g, 15.0 mmol) and DMF (75 mL) were added to a 100 mL round bottom flask. Under nitrogen protection, heat (140° C.) under reflux and stir for three days. After the reaction, cool to room temperature, add water, filter with suction, dry the solid, and then recrystallize with acetonitrile to obtain gray powder NA. Yield: 65%, melting point: >300°C.

[0046] (2) Synthesis of ZM: Add 240mmol (58.5528g) 1,6-dibromohexane and 40mmol KI (6.641g) to 400ml acetone, stir at room temperature for 30 minutes, then add 16.56g K 2 CO 3 (120mmol) and 30mmol hydroquinone (3.3033g), immediately with N 2 protection, the mixture was heated and refluxed at 65°C for 72 hours, after the reaction was completed, it was suction filtered while it was hot, and the filtrate was collected and concentrated, mixed with silica gel, spin-drying column chrom...

Embodiment 2

[0052] Embodiment 2, SOF-AP5-MJP5 to Fe 3+ Efficient separation and removal of

[0053] First configure the concentration as 1×10 -5 M Fe 3+ Aqueous solution 5mL, in Fe 3+ Add 0.13mg (5×10 -8 mol) dry gel, after shaking for 30 minutes, centrifuge at 10000r / min for 30 minutes to remove the solid, and keep the liquid for ICP (inductively coupled plasma), the results show that SOF-AP5-MJP5 has a 3+ Ion adsorption rate: 99.39%.

Embodiment 3

[0054] Embodiment 3, SOF-AP5-MJP5 to Fe 3+ Efficient identification of

[0055] In SOF-AP5-MJP5, add 0.5 equivalent of Mg respectively 2+ , Ca 2+ , Cr 3+ , Fe 3+ ,Co 2+ , Ni 2+ , Cu 2+ , Zn 2+ , Ag + , Cd 2+ , Hg 2+ , Pb 2+ , Ba 2+ , Al 3+ , La 3+ and Eu 3+ (0.1M) solution, if the yellow fluorescence of SOF-AP5-MJP5 is quenched, it means Fe was added 3+ , if the fluorescence of SOF-AP5-MJP5 does not change, it means that the addition of Min is not Fe 3+ .

Abstract

The invention designs and synthetizes a supermolecule polymer framework material. The supermolecule polymer framework material is formed through self assembly in cyclohexanol by using naphthalimide functionalized pillar [5] arene as a subject and bilateral quaternization pillar [5] arene as an object, wherein the mole ratio of the subject to the object is 1:1. Through competitive coordination mechanism, the supermolecule polymer framework material (SOF-AP5-MJP5) and a metal supermolecule polymer framework material (M-SOF-AP5-MJP5) can respectively realize continuous response and high-sensitivity detection to Fe<3+> and H2PO4<->; the recognition performance has important application values in the field of ion recognition.

Description

technical field [0001] The present invention relates to the preparation of a supramolecular polymer framework material, in particular to a pillar [5] arene (AP5) based on naphthalimide functionalization and a pillar [5] arene (MJP5) containing bilateral quaternization ) preparation of the supramolecular polymer frame material; the present invention also relates to the high-sensitivity continuous recognition Fe of the supramolecular polymer frame material 3+ and H 2 PO 4 - Applications. Background technique [0002] In the fields of chemistry, biology, environment, etc., ions and molecules play an important role, which is very important for the detection and separation of some special ions or molecules in the environment, such as: iron (Fe), which is an indispensable trace element for the human body , it is an important component of hemoglobin, myoglobin and various enzymes. If the body lacks iron, it can affect the synthesis of hemoglobin and myoglobin, and can make cert...
